CARL OLSEN, OF LONG ISLAND CITY, NE\V YORK.

INVALID-BED.

SPECIFICATION forming part of Letters Patent No.318,199, dated May 19,1885.

Application filed January 17, 188-1. ()Iodel.)

T0 aZZ whom it may concern.-

Be it known that I, CARL OLSEN, of Long Island City, in the county ofQueens and State of New York, have invented a new and ImprovedInvalid-Bed, of which the following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters 'of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of my invention ready for use, the commodebeing shown in broken lines. Fig. 2 is a plan view of the same, themattress and bolster being removed. Fig. 3 is a transverse sectionalelevation taken on the line 00 w of Fig. 1, and Fig. 4 is a detailedsectional plan View taken on the line y g of Fig. 3. Fig. 5 is a detailsectional view. Fig. 6 is a detail of the cam and the sliding plate towhich it isattached.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

The frame A and cross-bars A A of the bedstead are by preference made ofiron, and supported by the legs B in any ordinary manner. The slats O,springs D, and mattress E are of ordinary construction, except that themattress E has formed through it the opening F, and that one or more ofthe slats O are cut away immediately below the opening F to admit thepassage up through the slats of the commode G and cushion H, the latterserving to close the opening F when the commode G is not in use, theends of the slats cut away being supported by crossbars secured to theunder side of the slats. The commode G and cushion II are supported,respectively, upon the bifurcated arms I J, which are placed looselyupon the upright square rods K K, and are adapted to be raised andlowered on said rods by mechanism operated by the wormshaft L, foralternately raising and lowering the commode G and cushion II into andout of the passage F. The commode G and cushion H, when they reach thelowest positions, are swung outward, alternately, toward opposite edgesof the bed by said mechanism acting on arms I J, as illustrated in} fulland dotted lines in Fig. 2, the upright rods K K being pivoted at theirlower ends in the ends 8 s of the divided brace S and at their upperends in the bars B B (shown clearly in Fig. 3) for that purpose; and thearms I J are so arranged that while the arm J is being moved outward,carrying the cushion H toward the edge of the bed, the arm I will bemoved inward, carrying the commode under the ,passage F, and vice versa.At the time the commode is being raised up to and lowered from thepassage F the cushion II remains at rest, and at the time the cushion israised and lowered the commode in turn remains at rest. The mechanismfor accomplishing these movements of the commode G and cushion Hconsists of the said worm-shaft L, which is adapted to be revolved atone side of the bed'by the crank or hand wheel L, the worm-wheel M,arranged to be revolved by the worm on shaft L, the elliptical cam N,attached to the plate 0, arranged to slide upon the cross-bar A" of theframe of the bedstead, the stud a, attached to the worm-wheel M andrunning within the cam N, and the long arm or crank P, attached to thesaid worm-wheel so as to move outside of 7 5 cured to the upright rods KK, for turning the said rods alternately in opposite directions as theplate 0 is moved backward and forward upon the cross-bar A.

The operation is as follows: The commode G being elevated into theopening F, as shown in Fig. 3, the crank-wheel L will be turned to theright in the direction of the arrow shown in Fig. 1. This will turn theworm-shaft L, the worm of which will slowly turn the wormwheel M in thedirection of the arrow shown in Fig. 3,which will cause the arm or crankI (which is practically a part of the worm-wheel) to come upon the upperedge of the lower prong, b, of the bifurcated arm I and slowly slide orpermit the arm I to slide by its own weight and that of the commode Gdownward upon the rod K,accordingly as the crank P is ICO carrieddownward by the turning of the wormwheel M. When the crank P approachesits lowest point in its revolution, it will move off from the prong I),and'at this time the arm I and commode G will have reached the lowestpoint, the arm J resting upon the end s of the bifurcated brace S. Atthis time, also, the stud a will enter the notch 0 made at the lower endof the elliptical cam N, and as the wormwheel l\I continues to revolvewill carry the cam N and plate O,to which the cam is rigidly attached,to the right, the plateO sliding upon the cross-bar A of the frame ofthe bedstead. This movement of the plate 0 will cause the slotted lugs QQ to carry the outer ends of the cranksR R to the right, which will turnthe rods K K in their bearings, and carry the arm I and commode G to theedge of the bed to the position shown in dotted lines in Fig. 2, and atthe same time swinging the arm J and cushion H toward the center of thebed under the opening F. At this time the stud a will pass the notch c,and the crank I will come against the lower edge of the upper ,prong, d,of the bifurcated arm J, and will slide the arm J, as the wornrwhcel l\Icontinues to revolve, upward upon the rod K. thus lifting the cushion Hinto the opening F, closing the same, making the mattress complcte,asthough no opening F were made in it. At the upper part of the cam N isformed the stop 0, which prevents the worm-wheel M from being turned toofar in either direction, as will be understood from Fig. 3.

Upon reversing the direction of revolution of the crank-wheel L thereverse of the opera tion just described will take plaeethat is, theworm-wheel M will be turned in the direction opposite to that indicatedby the arrow in Fig. 3, which will first cause arm P to lower the arm Jand cushion H to the end 8 of the brace S. Then the stud a will enternotch c and move the cam N and plate 0 to the left, which will, throughlugs Q, Q and the levers R R1, swing the arm J and cushion H to theposition shown in all of the figures of the drawings, and at the sametime swing the arm I and commode G to the center of the bed immediatelyunder the opening F, and then the arm or crank I will lift the arm I andcommode G to the position shown in all the figures, with the commode Gfilling the opening F, i

The commode G is made with the covers g g pivoted to the body of thecommode by pivots g at the ends of the body. The covers 9 are eachformed or provided with an arm, 9, and the covers are adapted to bedrawn together for closing the commode, in this instance by the rubbercords g 9", attached to them, as shown in Fig. 2. The arms are forautomatically opening the commode at the time the commode enters theopening F in the mattress, and for this purpose I attach to theeross-bars A A of the frame of the bedstead the frame T,having inclinedwalls,which are slotted, as shown at t t, up through which frame thecommode G has to pass before entering the opening F. The arms 9 enterthe slots t and are carried to the upper ends thereof, where they areretained by the frame T,while the body of the commode is carried fartherup, which causes the covers {1 g to be opened against the tension of therubber cords g" g',so that when the commode is carried as far up intothe opening F in the mattress as it will go it will be automaticallyopened ready for use. Upon lowering the commode out of the frame T therubber cords g g will automatically draw the covers 9 9 together andclose the commode. The body of the commode is formed with the flaringbase 71, the lower. edge of which is adapted to fit under the convergingflanges of the supporting-plate j, secured to the arm I, where thecommode is securely held by the weighted pawl 1' ,as shown clearly inFig. 1,so that by operating the pawl i the commode may be removed fromthe arm I and replaced at pleasure, and for conveniencein removing andreplacing the commode, I adapt the arm I to be swung around upon the rodK to bring the platej from under the bed, and for this purpose I employthe sleeve is, which fits the square rod K, and 011 which the arm I ispivoted, and for carrying the arm I back in proper position to be actedupon by the lever P, I place the coiledspring Z upon the sleeve is andattach'its upper and lower ends, respectively,to the arm I and sleeve isin such manner that the swinging out of the arm I by hand for removingand replacing the commode G will be against the tension of the spring Z,and in order to stop the arm I at the proper position when swung backunder the bed by the action of the spring Z, I form the sleeve k withthe shoulder m, and the arm I with the stop-lip m, adapted to strikeagainst the shoulder m, as will be understood from Fig. 4-.

U is a Ushaped bolster'frame, attached at its ends to shaft V, journaledat its ends in the side plates, A A, of the frame of the bedstead, asshown in Figs. 1 and 2, and upon the shaft V is placed the worm-wheel'V, which meshes with the short worm-shaft IV, so that by turning thecrank 10 thereof the bolster'frame U and bolsterU,placed therein, may beraised and lowered for raising and lowering the patient, as required.

Constructed as described,'it will be seen that the bedstead is completefor its purpose, and the entire mechanism may be worked by the patientoccupying the bed by reaching to and operating the crank and hand-wheelL, which may conveniently be done.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combinatiomwith a bedstead, of the rods K K, attached to thebottom of the bedstead, the slottcd arms I .I, loosely mounted on saidrods and carrying a commode and cushion, respectively, a shaft journaled below the bedstead and provided with the crankarm 1?, and meansfor operating said crankarm, substantially 'as herein shown anddescribed.
